Introduction
Preliminary
Information
Features...
The Cyclone^TM field programmable gate array family is based on a 1.5-V,
0.13-µm, all-layer copper SRAM process, with densities up to 20,060 logic
elements (LEs) and up to 288 Kbits of RAM. With features like phase-
locked loops (PLLs) for clocking and a dedicated double data rate (DDR)
interface to meet DDR SDRAM and fast cycle RAM (FCRAM) memory
requirements, Cyclone devices are a cost-effective solution for data-path
applications. Cyclone devices support various I/O standards, including
LVDS at data rates up to 311 megabits per second (Mbps) and 66-MHz,
32-bit peripheral component interconnect (PCI), for interfacing with and
supporting ASSP and ASIC devices. Altera also offers new low-cost serial
configuration devices to configure Cyclone devices.
■ 2,910 to 20,060 LEs, see Table 1
■ Up to 294,912 RAM bits (36,864 bytes)
■ Supports configuration through low-cost serial configuration device
■ Support for LVTTL, LVCMOS, SSTL-2, and SSTL-3 I/O standards
■ Support for 66-MHz, 32-bit PCI standard
■ Low speed (311 Mbps) LVDS I/O support
■ Up to two PLLs per device provide clock multiplication and phase
shifting
■ Up to eight global clock lines with six clock resources available per
logic array block (LAB) row
■ Support for external memory, including DDR SDRAM (133 MHz),
FCRAM, and single data rate (SDR) SDRAM
■ Support for multiple intellectual property (IP) cores, including
Altera^ MegaCore^ functions and Altera Megafunctions Partners
Program (AMPP^SM) megafunctions
